Closed-eye Hallucination - Levels of CEV Perception

Levels of CEV Perception

There are five known levels of CEV perception which can be achieved either through chemical stimuli or through meditative relaxation techniques. Level 1 and 2 are very common, and often happen every day. It is still normal to experience level 3, and even level 4, but only a small percentage of the population do this without psychedelic drugs, meditation or extensive visualization training.

Famous quotes containing the words levels of, levels and/or perception:

    The country is fed up with children and their problems. For the first time in history, the differences in outlook between people raising children and those who are not are beginning to assume some political significance. This difference is already a part of the conflicts in local school politics. It may spread to other levels of government. Society has less time for the concerns of those who raise the young or try to teach them.
    Joseph Featherstone (20th century)

    In England we have come to rely upon a comfortable time-lag of fifty years or a century intervening between the perception that something ought to be done and a serious attempt to do it.
